Here’s a nice guide from Hector Matos called “Hipster Swift” that nicely explains some features of Swift code that you may often find when looking through someone else’s code, but may not fully understand.
The topics covered in the tutorial are:
– @noescape
– @autoclosure
– inline lazy vars
– currying
– variadic parameters
– the dynamic keyword
– special literals
– loop labels
You can find the tutorial over on the KrakenDev website.
